… for crate `clippy_lints`" compiletest error
ci: always build with internal lints group up internal lints in lib.rs dogfood: we already pass --all-features, no need to enable internal-lints again
add `internal-lints` feature to enable clippys internal lints (off by default) This PR moves the internal lint tests into a new subdirectory (I couldn't find a different way to compile-time-conditionally exclude them from compiletest) and only builds and tests internal lints if the `internal-lints` feature is enabled. Fixes rust-lang#6306 changelog: put internal lints behind a feature ("internal-lints")

Add Collapsible match lint changelog: Add collapsible_match lint Closes rust-lang#1252 Closes rust-lang#2521 This lint finds nested `match` or `if let` patterns that can be squashed together. It is designed to be very conservative to only find cases where merging the patterns would most likely reduce cognitive complexity. Example: ```rust match result { Ok(opt) => match opt { Some(x) => x, _ => return, } _ => return, } ``` to ```rust match result { Ok(Some(x)) => x, _ => return, } ``` These criteria must be met for the lint to fire: * The inner match has exactly 2 branches. * Both the outer and inner match have a "wild" branch like `_ => ..`. There is a special case for `None => ..` to also be considered "wild-like". * The contents of the wild branches are identical. * The binding which "links" the matches is never used elsewhere. Thanks to the hir, `if let`'s are easily included with this lint since they are desugared into equivalent `match`'es. I think this would fit into the style category, but I would also understand changing it to pedantic.
